The APS4 rear panel provides the following inputs and outputs:
DC IN 12 V/3500 mA: Input jack for an optional 12 V DC power.
ANTENNA A IN, ANTENNA B IN: BNC input connectors for SRA2 B/W, or RA4000 B/W
remote antennas. When using diversity receivers you will need two receiving antennas
(optional). Each antenna input provides a 12 V DC supply voltage for an active antenna.
ANTENNA A OUT TO SR: The four BNC connectors 1A through 4A deliver the antenna signals
for the A inputs of up to four diversity receivers. All unused outputs remain open. The cable
used in this case must not be longer than three meters.
ANTENNA B OUT TO SR: The four BNC connectors 1B through 4B deliver the antenna signals
for the B inputs of up to four diversity receivers. All unused outputs remain open.
In addition to the antenna signals, outputs 1A through 4A and 1B through 4B provide a 12 V
DC supply voltage for the connected receivers. The cable used in this case must not be longer
than three meters.
The current carrying capacity at each of the eight output jacks is one ampere. When on one /
multiple output jacks a DC short circuit occurs are respectively connected to this receiver goes
dead and the other receivers continue to function properly.
LINK A TO PS, LINK B TO PS: These two BNC outputs carry the RF signal of the two antennas
A and B. You can connect the LINK outputs to the antenna inputs of another APS4 antenna
splitter to daisy-chain several antenna splitters.
Please note that you must have a separate 12 V/3500 mA power supply for each APS4.
Passive and active directional antennas as well as passive and active omnidirectional antennas
are available for the APS4 antenna system. All antennas are wideband devices for the entire
UHF band.
The active antennas are powered by the APS4 antenna splitter via the antenna cables. For
complex systems with long antenna cables, we recommend powering each active
antenna from a decentralized 12 V/3500 mA power supply via an ASU4000 remote power
adapter.
The SRA2 B/W is an active directional antenna with a rugged, water-resistant case designed
specifically for indoor and outdoor use at a distance from the performance area. An integrated
high-performance antenna booster allows you to position the antenna up to 100 m (330 ft.)
away from the receiver. Using RG213 antenna cables and two AB4000 antenna boosters in
series, you can set up the SRA2 B/W even 200 m (660 ft.) away from the receiver.
The antenna provides a BNC output, status LED, and integrated stand adapter.
The RA4000 B/W is an active omnidirectional antenna with a rugged, water-resistant
case designed specifically for indoor and out- door use in close proximity to the performance
area. An integrated high-performance antenna booster allows you to position the antenna up
to 100 m (330 ft.) away from the receiver. Using RG213 antenna cables and two AB4000
antenna boosters in series, you can set up the RA4000 B/W even 200 m (660 ft.) away
from the receiver.
The antenna provides a BNC output, status LED, and integrated stand adapter.
